DEVICE FOR COUPLING METAL TIES.

Application filed June 1, 1918, Serial No. 237,735.

To all whom it may concern:

Be it known that I, WILLIAM GRUBB TURNER, a citizen of the United States, residing at Memphis, Shelby county, and State of Tennessee, have invented and discovered certain new and useful Improvement in Devices for Coupling Metal Ties, of which the following is a specification.

In the operation of securing the ends of metal bands or ties together in baling cotton, etc., it is desirable to draw said bands as tightly as possible around the compressed bale and secure them together while taut and before the compress is open.

The object of my said invention is to provide a mechanical device for twisting or doubling the lapped ends of the metal hands together while the bale is in the compress in such a way that the work may be done conveniently and expediently, all of which will be hereinafter more fully described and claimed.

Referring to the accompanying drawings which are made a part hereof, and on which similar reference characters indicate similar parts,

Figure 1 is a side elevation of a portion of the front of a compress showing one of my devices or machines in position for use;

Fig. 2, an edge elevation,

Fig. 3, a view partly in top plan and partly in horizontal section, and

Fig. 4, a view showing the ends of a band or tie as it appears after secured by my improved method.

In said drawings the portions marked A represent the upper platen, B the lower platen of the machine, and C the bale of cotton.

To each end of the front side of the upper platen is secured a bracket 10 having a horizontal arm 11 on which is mounted a hanger 12 having a sleeve 13 on its upper end adapted to slide on the arm 11 and a sleeve 14 on its lower end in which is supported a horizontal bar 15 on which the body of the machines are mounted. said machines comprise a frame 16 in which is journaled a shaft 17 on which is keyed a gear having double faces 18 and 19, as shown.

Another shaft 20 is journaled in bearings in the inner ends of the side pieces of the frame, one end of which shaft is bifurcated forming a twisting tool 21 which is adapted to embrace the lapping ends 22 and 23 of Specification of Letters Patent.

the tie. A beveled pinion 24 is keyed to one end of shaft 20 and a beveled gear 25 is loosely mounted on its other end and has an internal spiral groove 26 adapted to normally abut against a threaded portion 33 on said shaft.

An operating handle or arm 27 is mounted in the upper side of the casingor frame and has an inner end 28 which engages in an annular groove 34 in the double faced gear fOr the purpose of sliding said gear back and forth on shaft 17.

In operation the tool or machine is hung upon bar 15 and adapted to slide back and forth thereon. The bar 15 carrying the tool or a series of tools (preferably one for each man) is adapted to slide in and out, toward and from the bale on the horizontal arms 11. A pin 29 inserted in the outer end of said arm prevents the sleeve 13 from sliding off.

The machine is slid in and adjusted until the bifurcated end 21 of the shaft embraces the lapped ends of the tie when gear face 19 is slid into engagement with gear 24 through the medium of the handle 27 when shaft 17 is rotated, e'ther by poweror by hand as may be pre erred, which operates to turn the shaft 20 and double over the lapped ends of the metal bands one upon the other as illustrated in Fig. 4. The metal clamp 30 which has previously been threaded onto the tie is slid down until its notches 31 in its opposite edges pass over the edge of the twisting tool 21 and secure the lapped or folded ends from expansion. The double faced gear is then slid until gear face 18 meshes with gear 25 which operates to turn said gear 25 and the spiral groove 26 threading onto spiral thread 33 operates to withdraw shaft 20 so that its bifurcated end will become free from engagement with the metal bands.

Bv this means the metal bands may be readily and rapidly doubled or twisted one upon another and drawn taut around the bale and secured by the clamping buckle 30 in a convenient and expeditious manner.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

1. A tool for doubling or twisting metal bands or ties comprising a frame, a shaft carrying a twisting tool adapted to embrace lapped ends of the bands or ties, a gear for rotating said tool and a gear adapted to withdraw said tool from engagement with said bands when desired, substantially asset tool is mdunted to also have a longitudinal movement, and gearing rotating said tool by a spiral connection whereby it may be slid longitudinally to free itself from said bands.

or ties, substantially as set forth.

3. A mechanical device for twisting 0r doubling the lapped ends of bale ties comprising a frame, a rotary tool journaled in said frame and provided with jaws adapted to embrace the lapped ends of the tie, a double-faced gear on a power shaft, a gear on the twisting shaft adapted to engage with one face of said double-faced gear after imparting a rotary movement to said twisting shaft, and another gear on said shaft connected thereto by a spiral connection adapted to engage with. the other face of said gear for sliding said shaft longitudinally, substantially as set forth.

4:. A machine for twisting lapped ends of ties comprising a twisting tool mounted to rotate and slide, and means for operating said toolin both of said directions, substantially as set forth.

In witness whereof, I have hereunto set my hand and seal at Washington, District of Columbia, this twenty-third day of May, A. D. nineteen hundred and eighteen.

WILLIAM GRUBB TURNER.
